Abstract:

L'objet de ma thèse, réalisée en collaboration avec l'industriel VALEO, est de développer des systèmes d'aide à la conduite pour accroître la sécurité et le confort à bord des véhicules. Pour résumer, il s'agit d'élaborer des algorithmes de contrôle longitudinal de type Adaptive Cruise Control (ACC) permettant de suivre en temps réel avec sécurité un véhicule leader et plus généralement d'élaborer des stratégies à basse vitesse (Stop&Go) pour l'évolution du véhicule dans des environnements urbains. À basse vitesse, le problème de l'aide au parking de type ‘créneau' a été également considéré. Dans un premier temps, les algorithmes de contrôle longitudinal (ACC et Stop&Go) ont été étudiés. Aﬁn d'accroître la robustesse du système contre les bruits de mesure, les dynamiques négligées externes comme la pente de la route, la résistance aux roulements et la force aérodynamique etc. , ainsi que les incertitudes liées au modèle moteur/frein, les techniques d'estimation algébrique et de commande sans modèle ont été appliquées. En ce qui concerne l'automatisation à basse vitesse de type ‘parking en créneau', nous avons proposé une solution générale basée sur une approche géométrique. Notre planiﬁcateur local permet de générer un chemin géométrique composé d'arcs de cercles de rayon minimal et de segments de droite pour une place de parking dont la longueur est plus grande que la diagonale du véhicule. Il faut remarquer que notre méthode est indépendante de la position initiale du véhicule si sa position initiale est parallèle à la place de parking. Un algorithme planiﬁant un chemin géométrique pour le problème de parking en créneau en fonction de la longueur de la place de parking a été également développé. Une étude théorique de la complexité de notre méthode en terme de nombre de manœuvres montre qu'elle nécessite moins de manœuvres que des méthodes classiques dans les cas pratiques The purpose of my thesis, realized in collaboration with VALEO, is to develop advanced driver assistance systems to increase safety and comfor t in vehicles. To summarize, it is to develop algorithms of a longitudinal control such as Adaptive Cruise Control (ACC) allowing to follow in real time with a safety a leading vehicle and more generally strategies to lower Speed (Stop&Go) for the evolution of vehicle in urban environments. At low speed, it should also consider the problem of parallel parking assistance. First of all, the longitudinal control algorithms (ACC and Stop &Go) were studied. In order to increase system robustness against measurement noise, neglected external dynamics such as the slope of the road, rolling resistance and aerodynamic forces, etc. , as well as uncer tainties related to the engine/brake model, an unﬁed algebraic approach for estimation and model-free control is applied. Regarding the low-speed automation of parallel parking, we proposed a general solution based on a geometric approach. Our local planner can generate a geometric path consisting of circular arcs of minimum radius and straight lines for a parking space whose length is greater than the diagonal of the vehicle. It should be noted that our method is independent of the initial position of the vehicle if its initial position is parallel to the parking lot. An algorithm for geometric path planning of the parallel parking problem according to the length of the parking space was also developed. A theoretical study of the complexity of our method in terms of the number of maneuvers shows that it requires less maneuvers than classical methods in practical cases

Abstract:

This thesis presents a new nonlinear automobile dynamical model and investigates the possibility of automobile dynamic control with wheel torque utilizing this model. The model has been developed from first principles by applying classical mechanics. Inputs to the model are the four independent wheel torques, while the steer angles at each wheel are specified as independent time-varying signals. In this way, consideration of a variety of steering system architectures, including rear-wheel steer, is possible, and steering introduces time-varying structure into the vehicle model. The frictional contact at the wheel-road interface is modeled by use of the LuGre dynamic friction model. Extensions to the existing two-dimensional LuGre friction model are derived and the steady-state of the friction model is compared to existing static friction models. Simulation results are presented to validate the model mathematics and to explore automobile behavior in a variety of scenarios. Vehicle control with wheel torque is explored using the theory of input-output linearization for multi-input multi-output systems. System relative degree is analyzed and use of steady-state LuGre friction in a control design model is shown to give rise to relative degree singularities when no wheel slip occurs. Dynamic LuGre friction does not cause such singularities, but instead has an ill-defined nature under the same no-slip condition. A method for treating this ill-defined condition is developed, leading to the potential for the system to have relative degree. Longitudinal velocity control and combined longitudinal and angular vehicle velocity control are demonstrated in simulation using input-output linearization, and are shown to produce improved vehicle response as compared to the open-loop behavior of the automobile. Robustness of the longitudinal velocity control to friction model parameter variation is explored and little impact to the controller's ability to track the desired trajectory is observed.

Abstract:

Au-delà des apparences, les clubs automobiles de prestige en France sont des espaces culturels ouverts à un public hétérogène venu partager une même passion pour une même marque. Les membres, propriétaires ou sympathisants, se rassemblent autour des voitures ayant marqué l'histoire sociale. Leur caractère mythique est précieusement conservé par la pratique rituelle des sorties organisées par ces tribus modernes. Les clubmen préservent ce patrimoine immatériel lors des grands rassemblements au cours desquels ils réactualisent les événements ayant élevé l'automobile au rang d'Objet de prestige, d'Objet sacralisé. Le club est le mémorial de l'automobile ; il est, à la fois, l'espace de la dynamique de la pratique et de l'effusion passionnelle. Les souvenirs des événements liés aux automobiles et à l'enfance, que nous avons définis par l'ethos de la nostalgie, nourrissent cette passion qui est partagée, aussi, par les femmes, ces conductrices du troisième millénaire. Le rapport à l'Objet est de l'ordre de l'intime. Les clubs ont pour finalité de transmettre une culture automobilistique, mais aussi de conserver ce patrimoine industriel autour d'une pratique qu'est l'automobilisme Far beyond the appearances, the motor-car clubs of prestige in France are cultural spaces open to an heterogeneous public of fans, who come to share the same passion for an identical model. The participants, members or only followers, gather around cars that have marked the social history. The mythical character of those modern tribes is preciously maintained by the ritual habit of organizing runs out. The clubmen keep this non-material patrimony by means of huge gatherings during which they bring back the events that promoted the motor-car up to the rank of an Object of prestige, a sacralised Object. The club is the motor-car memorial; it is, altogether, the space for practicing dynamics and passionate bursts. The memory of events linked to motor-cars and childhood, witch we define as the custom "ethos" of nostalgy, feed their passion, also shared by women, the third millenium drivers. The relationship to the Object is an intimate one. The purpose of the clubs is to transmit a car culture, and also to preserve this industrial patrimony by means of a custom which consists in motoring

Abstract:

Cette thèse aborde les défis liés à la conception des futures architectures électriques/électroniques automobiles, en se concentrant particulièrement sur l’estimation des ressources de calcul au cours des premières phases de conception. L’étude passe en revue l’évolution historique des architectures E/E, soulignant la complexité croissante et les limites des systèmes décentralisés traditionnelsau cours de l’évolution de l’industrie automobile. L’énoncé du problème souligne la nécessité d’une estimation précise des ressources informatiques au début du processus de conception, en particulier dans le contexte des demandes de devis de l’industrie automobile. Les méthodologies actuelles sont évaluées et jugées insuffisantes pour répondre aux exigences des futurs systèmes automobiles centralisés. Par conséquent, une question de recherche est formulée pour guider le développement d’une nouvelle méthodologie visant à améliorer la précision et l’efficacité de l’estimation des ressources. La méthodologie proposée fonctionne comme un guide de décision de haut niveau et incorpore le paradigme du temps d’exécution logique (LET) pour assurer une communication déterministe sur les plates-formes multicoeurs. Cette approche tient compte des contraintes propres aux systèmes automobiles, notamment les contraintes de temps réel, d’exécution, d’espace et d’utilisation des ressources. La méthodologie vise également à prendre en compte l’évolutivité du système dès le début de la conception en explorant les stratégies de partitionnement et d’affectation This thesis addresses challenges in designing future automotive Electrical/Electronic architectures, particularly focusing on estimating computational resources during early design. The study reviews the historical evolution of E/E architectures, highlighting the increasing complexity and the limitations of traditional decentralized systems as vehicles evolve. The problem statement emphasizes the need for accurate computational resource estimation early in the design process, particularly within the context of request for quotations in the automotive industry. Current methodologies are evaluated and found lacking inaddressing the demands of future centralized automotive systems. Consequently, a research question is formulated to guide the development of a new methodology for improving resource estimation accuracy and efficiency. The proposed methodology functions as a high-level decision guide and incorporates the Logical Execution Time (LET) paradigm to ensure deterministic communication on multi-core platforms. This approach addresses the unique constraints of automotive systems, including real-time, execution, spatial and resource utilization constraints. The methodology also aims to account for system scalability duringearly design by exploring partitioning and assignment strategies

Abstract:

Thesis (M.B.A.)--Massachusetts Institute of Technology, Sloan School of Management, 2011. Cataloged from PDF version of thesis. Includes bibliographical references (p. 37-38). Marketing alternative fueled vehicles is a difficult challenge for automakers. The foundation of the market, the terms of competition, and the customer segments involved are still being defined. But automakers can draw lessons from other industries, previous examples, and recent launches of the Chevy Volt and Nissan Leaf to help guide them. Automakers can deploy new marketing tools to advance their understanding of the market, define the terms of competition, and listen in to their customers' needs. These new tools can help reduce the risk and uncertainty involved with launching new products like alternative fueled vehicles. This thesis explores the major issues in marketing alternative fueled automobiles in several major parts. First it will look at the major drivers of alternative fueled vehicles and historical examples such as the Prius. While the market continues to change with each year, some trends emerge as key to defining the future of the industry. Second, it will look at the current strategic environment for alternative fueled vehicles, including an exploration of the various fuel types and vehicle offerings. Third, it will offer lessons learned for manufacturers based on the case study work done with two automotive manufacturers on real-life launches of a plug-in hybrid and a hydrogen vehicle. Some classical marketing frameworks, such as the innovation cycle, are used to help understand current puzzles, and new tools, such as semantic/perceptual maps, are used to help understand how open questions might be resolved in the next few years. Finally, it will explore a novel modeling tool developed for assessing potential adoption rates for alternative fueled vehicles by looking at costs and profits from both the owners and automakers' perspective. by Alex Zheng.

Abstract:

Das Ziel dieser Dissertation ist die systematische Entwicklung eines weiterführenden Konzeptes zur Fahrer-Fahrzeug Kooperation, dessen Tauglichkeit anhand empirischer Daten evaluiert und im Hinblick auf sein belegbares Potential in Bezug auf bestehende Ansätze bewertet werden soll.Da Annahmen und Prämissen der Mensch-Maschine-Interaktion den Ausgangspunkt bilden, beginnt die dezidierte Auseinandersetzung und begriffliche Differenzierung von Kooperation in eben diesem Kontext und führt folgerichtig zu einer definitorischen Abgrenzung gegenüber existierenden Ansätzen, der Forderung eines spezifischen Rollenverständnisses zur Interaktion sowie der Ableitung konzeptueller Grundbedingungen. Anschließend werden die strukturellen und prozeduralen Merkmale dieser spezifischen Interaktion herausgearbeitet und dazu benutzt, die generellen Attribute von Kooperation zwischen Fahrer und Fahrzeug zu identifizieren. Dafür wurden nachfolgend solche Indikatoren abgeleitet, vermittels derer der unterstellte Gewinn infolge der Kooperation von Fahrer und Fahrzeug kontrolliert und bewertet werden kann.Im Rahmen mehrerer Voruntersuchungen wurden Fahrsituationen identifiziert, die am meisten von einer kooperativen Interaktion zwischen Fahrer und Fahrzeug profitieren würden. Im Ergebnis wurden für die zwei Hauptuntersuchungen das „Überholen auf der Autobahn“ und das „Linksabbiegen auf innerstädtischen Straßen und Landstraßen mit Gegenverkehr“ als Fahrszenarien ausgewählt, die in jeweils einem eigenständigen Experiment mit alternativen Systemvarianten verglichen worden sind. Die Prüfung spezifischer Hypothesen wurde dabei in die prototypische Umgebung eines Fahrsimulators eingebettet. Abschließend werden in dieser Arbeit die Möglichkeiten zur Etablierung und Einbettung dieses Interaktionskonzeptes in den übergreifenden sozio-technischen Kontext aufgezeigt und zukünftige Perspektiven diskutiert. The aim of this dissertation is to systematically develop a continuative concept of driver-automobile cooperation, to evaluate its suitability on the basis of empirical data, and to value its provable potential in relation to existing approaches.Assumptions and premises regarding the human-machine interaction constitute the starting point of this work. The decisive altercation and notional differentiation of cooperation are explained in just this context, leading logically to a definitional demarcation of existing approaches, the demand of a specific role understanding of the interaction as well as the derivation of conceptual basic conditions. The structural and procedural characteristics of this specific interaction are then elaborated upon and used to identify the general attributes of cooperation between driver and automobile. In the following, such indicators are derived by which the implied profit as a result of cooperation between driver and automobile can be controlled and valued. Within the framework of several preliminary investigations, those driving situations were identified that would profit most from a cooperative interaction between driver and automobile. As a result, the two driving scenarios "Overtaking on Highways" and "Turning Left on Urban and Country Roads with Oncoming Traffic" were utilized in the experiments. Both single scenarios have been compared in independent experiments with regard to alternative system variants. The prove of specific hypotheses was embedded in the prototypical surroundings of a driving simulator. Finally, the possibility of establishing and embedding this interaction concept into the overall socio-technical context will be presented, and future perspectives will be discussed.

Abstract:

Le travail presente dans ce memoire concerne l'etude du precontionnement thermique d'un habitable automobile en vue d'une reduction de la charge thermique tout en ameliorant le confort d'acceuil des passagers. Pour cela, un modele numerique, thermhab, a ete developpe. Celui-ci consiste en l'assemblage de differents codes de calculs permettant de traiter independamment l'ensemble des transferts de chaleur, et de les coupler dans un logiciel de resolution globale. L'outil final associe un modele zonal pour la representation des transferts de masse au sein du vehicule, un modele unidirectionnel aux differences finies pour les echanges conductifs, un modele rayonnement qui permet le calcul des facteurs de transferts (methode des revetements) ainsi que de la repartition des taches solaires dans l'abitacle, et enfin, un module de caracterisation du climat autour des passagers. Apres une validation du logiciel thermhab, son exploitation a permis une meilleure comprehension des phenomenes physiques au sein du vehicule. Les principaux resultats sont l'appartition d'une contradiction entre le traitement thermique de l'habitacle en hiver et en ete. Du point de vue du confort, les echanges convectifs et par rayonnement sont essentiels. Une recherche bibliographique portant sur des systemes passifs et actifs a ete egalement entreprise. Les technoilogies adaptees au preconditionnement thermique ont ete simulees sous thermhab. Les nombreuses simulations decoulant de ce travail montrent la possibilite de maintenir l'habitacle a une temperature proche de l'ambiante avec uniquement des technologies passives (gain en consommation jusqu'a 30%) ; l'utilisation de systemes actifs etant judicieuse uniquement en association avec des systemes repose sur la repartition de l'energie frigorifique ou calorique sur les parois et l'air interne de l'habitacle. Ceci permet de reduire legerement la consommation energetique pour un niveau de confort thermique ameliore.

Abstract:

La recherche de plus grandes performances des véhicules haut de gamme, notamment en termes de tenue de route et de confort, conduit à une amélioration du comportement élastocinématique des trains roulants. Outre la maîtrise des mouvements de caisse et des positions des roues par une cinématique efficace, la tendance actuelle est de recourir à un réglage statique en carrossage négatif pour garantir une meilleure adhérence des pneus en virage et contrer les effets de la souplesse de l'essieu. La nouvelle géométrie de train roulant OCP (Optimised Contact Patch) a pour but de dépasser cette solution classique en permettant la prise de contre-carrossage de manière active. En fait, les roues de l'essieu adoptent en temps réel la posture optimale pour garantir en toutes circonstances de meilleures conditions de fonctionnement du pneumatique sans apport extérieur d'énergie. Les travaux présentés dans ce mémoire de thèse concernent la modélisation et la mise au point d'une méthodologie de synthèse pour le développement de cette nouvelle architecture. Ce travail tient compte d'un cahier des charges élastocinématique adapté au type de véhicule sur lequel nous souhaitons implanter le nouvel essieu. L'analyse approfondie de sa cinématique et le besoin d'améliorer ses performances nous ont conduit à trouver une nouvelle architecture en vue de la contruction d'un prototype. Les mesures expérimentales de ce dernier ont permis de mettre en évidence l'efficacité de notre méthodologie et de nous pencher sur la localisation du centre de roulis

La thèse évoque les problématiques liées à la thermique des alternateurs d'automobile. En particulier, un modèle aéro-thermique est mis en place pour la machine. Les transferts thermiques de type conductif, convectif et fluidique sont caractérisés par des méthodes numériques, expérimentales ou encore issus de la bibliographie. Une comparaison avec des essais expérimentaux est proposé pour valider le modèle établi. Puis, une étude sur l'amélioration du refroidissement du stator et du rotor est présentée. Concernant le premier, le travail consiste à augmenter l'évacuation de la chaleur au niveau des têtes de bobine par modifications de paramètres géométiques (tel que la position du ventilateur). Pour le deuxième, l'étude s'est principalement focalisée sur l'augmentation du débit d'air axial et l'impact sur la thermique rotor.

Abstract:

Thesis (MTech (Industrial Design))--Cape Peninsula University of Technology, 2016. Simulators are used for many different purposes, among them physical rehabilitation and the training of differently abled learner-drivers. In South Africa, however, the extent of the latter type of simulators is limited to paraplegic learner-drivers only. The reason is that locally sourcing the necessary equipment to adapt commercial simulators for the training of differently abled learner-drivers presents a problem. The concept of Universal Design stipulates that as many individuals as possible should be able to use a particular product. Consequently, a simulator for differently abled learner-drivers should accommodate as many such persons as possible. However, applying Universal Design in the area of design researched for the present dissertation adds further complexity due to the unique nature of the physical limitations experienced by individuals. A differently abled driver puts an extreme constraint on the design of a product - and becomes a limiting user. Nevertheless, this dissertation adopts a Universal Design approach to investigate the possibility of designing such a simulator in South Africa, as well as its viability. A limiting user was included in the research to represent the bigger differently abled community. Field research was carried out by implementing a Participatory Design process. Furthermore, a team was selected according to a Meta-Design mind-set, including professionals from engineering, clinical psychology and occupational therapy. The leader and researcher was an industrial designer.

Abstract:

This thesis investigates the operation of a system of second hand car dealer licensing introduced to Scotland in 1982. The aim is to assess whether or not this policy is having a beneficial impact upon the experiences of second hand car purchasers in Scotland. The second hand car trade exhibits a number of characteristics of market failure with respect to consumer's interests. The complexity of the product and the infrequency of purchase make information about both product and dealer particularly difficult to obtain and evaluate. One regulatory response to consumer problems in this market is to licence second hand car dealers. This approach has been adopted in a number of other countries notably, Canada, Australia and some states of the US. The policy has provoked a great deal of debate about the achievement of consumer benefits associated with information and standards as opposed to producer benefits associated with restrictions to entry and mobility. In the Scottish case the power to licence second hand car dealers was delegated to Scottish district councils who were able to take advantage of considerable discretion in designing, implementing and operating their own licensing system. When seen from a national perspective, this delegation has led to a number of undesirable consequences. This thesis presents two major findings. The first is that district councils in Scotland have largely neglected their licensing systems. As a result the licensing of second hand car dealers in Scotland is only partially operative. The second is that second hand car dealer licensing in Scotland is having no impact upon the purchase experiences of consumers. There are two implications of these findings. First, without a fully operational system no evaluation of licensing as a policy is possible. Secondly, far from being unaffected by this partially operating system, consumers are worse off than without licensing. This raises issues for consumers, district councils and policy makers.

Abstract:

Afin de s'imposer dans un marché de plus en plus concurrentiel, chaque constructeur automobile tente de se distinguer par les sensations de plaisir de conduite que peuvent procurer les véhicules qu'il conçoit. Ainsi, l'agrément de conduite lié au comportement du groupe motopropulseur est une des prestations clients phares d'un véhicule. Cependant, la prise en compte de l'agrément de conduite dans le cycle de conception d'un véhicule automobile n'est pas aisée dans la mesure où le résultat de confort dépend de l'optimisation de l'ensemble du véhicule et pas seulement de chacun des sous-systèmes (moteur, boîte de vitesses,. . . ). L'objet de cette recherche concerne l'aide à la conception du groupe motopropulseur et de sa commande en vue d'optimiser l'agrément de conduite. Il consiste en une rélfexion générale sur l'utilisation de la modélisation, des outils d'analyse et de simplification de modèles dynamiques. La problématique de cette prestation est actuellement traitée à l'aide de représentations relativement simples. Ce travail propose des niveaux de modélisation plus évolués. Une étude bibliographiqe concernant les représentations des différents sous-systèmes influençant l'agrément de conduite d'un véhicule permet d'établir un modèle complet de véhicule. Pour chaque sous-prestation étudiée (à-coups en rapport engagé, décollage et passage de vitesses), différents modèles de synthèse sont proposés. L'introduction d'outils d'analyse comme l'observation des index d'activité des éléments énergétiques du système (inerties, raideurs, dissipations) contribuent à l'élaboration d'un niveau de complexité juste nécessaire à la représentation des phénomènes étudiés. Les modèles générés permettent non seulement de reproduire le comportement du véhicule en accord avec les résultats expérimentaux établis mais aussi de dégager des analyses et de mettre en évidence des phénomènes comme l'interaction entre la dynamique de la chaîne cinématique, le mouvement du groupe motopropulseur et la suspension horizontale de roue. De plus, l'influence des paramètres de conception des différents sous-sytèmes et l'analyse du comportement dynamique global du véhicule est menée. Finalement, cette étude doit permettre d'améliorer la compétitivité des secteurs d'ingénierie en apportant une meilleure compréhension du comportemnent du véhicule Powertrain driveability is considered as one of the most important customer requirement of a vehicle. In fact, in a more and more competitive market, any car manufacturer tries to distinguish himself by improving the driving pleasure felt by its customer. However, the consideration of the powertrain driveability during the vehicle design cycle is not coarse because this customer requirement is a consequence of the optimisation of the global vehicle and not only of each subsystems (motor, gearbox,. . . ). The aim of this research concerns the use of dynamical modelling, analysis and simplification tools in order to herlp vehicle conception engineering departments to optimise the powertrain driveability. This work proposes more complex vehicle models. Based on a bibliographical study concerning representations of the various subsystems influencing the powetrain driveability, a complete vehicle model is built. For every studied sub-performance (tip-in or tip-out, takeoff, and gearshift), various proper models are proposed. The use of modelling and analysis tools like activity index of each energetic elements of the system (inertia, stiffness, dissipation) permits to select the good model complexity level to simulate the studied phenomena. Generated models enable not only to reproduce vehicle behaviours in agreement with our experimental results but also to analyse and to put in focus phenomena like interaction between the driveline dynamic, powertrain movements and wheel horizontal suspension. Moreover, influence of conception parmeters of various sub-systems can be study with the use of those proper models. An analysis of global dynamic behaviours of the vehicle is then performed. Finally, this study improves the comptetitiveness and of engineering departments by bringing better understantig of the global vehicle behaviour in upstream phase of vehicle design cycle

Abstract:

The research is in two parts : in the first part entitled : the insurance contract we study the relation between the insurer and the insured. The second part deals with the rights of the injured party to compensation. Thus the conclusions of the thesis can be expressed in a few short, but meaningful terms, i. E the increasing role of insurance the decline of liability and the increased rights of the injured party to compensation in french law in terms of compulsory motor insurance and liability. And so thr theory according to which the interest of the injured party would be better defended in a system of insurance where by the risk theory is applied is no longer valid. In irak the risk theory is applied but many of the victims are deprived of their right to compensation because the lawmakers maintain the principale of default Les resultats du travail sont exposes en deux parties : dans la premiere partie, intitulee le lien d'assurance, nous avons etudie la relation entre l'assureur et a l'assure; la deuxieme est consacree au droit de la victime a l'indemnisation. L'aboutissement de la these s'exprime ainsi par des propos brefs, mais significatifs: l'accroissement du role de l'assurance, le declin de la responsabilite et l'elargissement du droit de la victime a l'indemnisation que nous constatons en droit francais en matiere d'assurance obligatoire et de responsabilite automobile. Ainsi la vulgate, selon laquelle, l'interet de la victime serait mieux protegee dans un systeme d'assurance ou la theorie du risque est appliquee, n'est plus valable. En effet, on a pu constater qu'en irak, malgre que l'assurance est automatique, fondee sur la theorie du risque, plusieurs victimes sont encore privees du droit a l'indemnisation. Car, le legislateur a maintenu la notion de la causalite de l'accident, c'est a dire que le vehicule doit causer l'accident. Nous constatons, enfin, que la loi de la convention de la haye du 4 mai 1971, relative a la determination de la responsabilite civile automobile en cas d'accident international, a pu etablir des principes de rattachements souples. Mais, au niveau de la forme, certaines dispositions meritent d'etre refondues
